BRIEF BAGS Filed July 6, 1962 INVENTOR MURRY J. BRENNER United States Patent 3,176,741 BEEF BAGS Murry .l. Brenner, 2024 S. Wabash Ave, H ghland Farlr, Ill. Filed .Iuly 6, I962, Ser. No. 207,9lltl 2 Claims. (Ill. Edd-1.6)

This invention relates to improvements in brief bags.

One of the objects of this invention is to provide a brief bag having means to cause the jaws of the brief bag to move to open position when the locking or other means holding the jaws closed are released.

Another object of this invention is to provide a very simple and inexpensive method and means for biasing the jaws of a brief bag or the like to open position.

Other objects and advantages will become apparent as this description progresses.

In the drawings:

FIGURE 1 is a perspective view of a portion of the brief bag embodying this invention.

FIGURE 2 is a view partly in section showing the jaws of the brief bag biased to open position by means of this invention.

FIGURE 3 is a plan View showing the features of this invention.

FIGURE 4 is a view similar to FIGURE 3 but in crosssection, and

In the embodiment shown, the outer jaw member is of generally U-shaped configuration, having side members 12 connected by a cross-member 14, all integrally formed and of substantially rigid material. The inner jaw member 16 is similarly constructed and comprises side members 18 connected by a cross-member Ztl, all

integrally formed. These jaw members are covered by leather or other suitable covering which is stitched to the side and end walls of the bag, as is well understood in the art. The inner jaw member 16 is adapted to nest or telescope within the outer jaw member it) when the jaws are in closed position, as seen in FIGURES land 5. This is all conventional.

The two jaw members ill and 16 are connected or hingedly joined together at their inner ends by a pin at each side. The pin is generally indicated at 22. pin 22 has a head 24 and an annular body portion 26 which passes through alined openings 28 and 36 at the inner ends of the sides 12 and 18, respectively, of the outer and inner jaws 1th and 16. The head portion 24 of the pin rests against the outside of the side of the outer jaw member. The opposite end of the pin 22 is peened as at 32 and a washer 34 is interposed between the inside side it? of the inner member 16 and the peened portion 32 to retain the pin thereon.

A coil spring generally indicated at 36 and having a number of coils is mounted on the pin 22 between the two adjacent sides 12 and 18 of the outer and inner jaw members 10 and 16. One end of the spring 36 terminates in an extension 33 having a right angled end 40 which seats within an opening 42 in the side 12 of the outer jaw member 10. The opposite end of the spring 36 terminates in an extension 44 having an outwardly right angled extending end 46 which seats within an opening 48 in the The 3,l7b,74l Patented Apr. 6, 1965 side 18 of the inner jaw member 16. The aforementioned connection is such that the jaw members: are biased by the spring 36 to maintain the jaw members in an open position, that is, with the jaws away from each other, as best shown in FIGURE 2.

The ends 4t? and 46 of the spring 36 are anchored in the sides of their respective jaw members so that the opposite spring terminals are affixed to the jaws and move with the jaws.

When the brief bag is in closed position, as shown in FIGURE 1, the inner jaw member 16 is telescoped within the outer jaw member l9 and the bag is held inclosed position by means of the securing strap 50 engaging the locking member 52. The strap 50 is secured to the side of the bag which is connected to the outer jaw member 10. In this closed position the spring member 36 is under tension or compression.

Upon unlatching of the strap with respect to the lock, the spring 36 will urge the two jaws 1d and 16 to open position or away from each other, as best shown in FIG- URE 2, so that the bag is open. This open position is maintained at all times, until such time as the two jaw members are brought together to close.

The open position, as shown in FIGURE 2, is wide enough to permit access to the interior of the bag, which is obtained through the opening between the jaw members. However, the jaw members may be further opened relative to each other and kept open by moving the jaw members outwardly away from each other so that th inner portions of the jaw members adjacent the pins are moved upwardly beyond the center.

While only one end of the bag is shown, it will be understood that the same structure is duplicated at the other end not shown.

It will be understood that various changes and modifications may be made from the foregoing without departing from the spirit and scope of the appended claims.

What is claimed is:

'1. A brief bag including a pair of jaws comprising an outer jaw and an inner jaw, each said jaw having side Walls and inner ends, said inner jaw telescoping within the outer jaw when in closed position, a pin member secured to the inner ends of said jaws for connecting said jaws for pivotal movement relative to each other, a s ring having opposite ends, said spring encircling said pin and positioned between the side wallsof the inner and outer jaws, said spring having its opposite ends anchored to the side walls of said inner and outer jaws to normally urge said'jaw, members away from each other and in open posit-ion.

2. In a structure described in claim 1, in which the opposite ends of the spring have extensions and right angled ends with said ends each being secured in an opening in the side walls of said respective jaws.
